To itz lwhom iifi ietcty coitceffl; I Begit known that I, 'VVILLIAM H. LIMBERG,' a CllJl-ZGIIOEl the'UnitedS tates, residing at Plymouth, in the countyjof Sheboygan and iState of Vl isconsin, have invented a new and useful'Mold for Making Solid Concrete Silos,

-of which the following is a specification.

This invehtionjrelates to moldsfor making "silos and similar structures from cement, concrete and other plastic material and has for its object to provide a strong durable set up for use and. uickly' knocked down and 'compa ctly assemb ed" for transportation or shipment A further object is toi'provide' ,means for locking the adjacent mold sectionsin engagement with each other and means for preventing lateral displacement of said sections.

- Afu'rther object isto provide a plurality of spaced tie-rods for reinforcing and strength enin'gthe' silo and further to form the interior walls of the silo with a longitudinally dispo'sed seating'recessfor the reception of the doors of the silo."

; I 'A still further objectof the invention is to generally improve: this class of molds so as to increase their utility, durability and efficiency.. 5 v

-Further objectsand-advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to;,wi-thin the scope of the I ner and outer'shell members 5' 'and 6;:.are,-.J95

The improved mold forming the subject matter of the present invention includes an outer shell member 5 and an inner shell member 6, said members being spaced apart to rations for the reception of suitable connect .formed in two sections:15;-an d 16 andywhi Fig. 3'is a detail vertical secj and provided with inclined faces .-1;7 adapted 'to form a correspondingly shaped eseatingfrre the latter.

The inner and outer shell membe- 5 and 6 are preferably constructed of galvanized-iron or'other suitable material and are eachpreferably formed of a plurality of sectionsol segments 8 having theiro posite ends reinforced and strengthened y vertically dis- 5, posed angle-bars 9 which may begflveted, bolted or otherwise rigidly secured to the sec: tions, as ,shown. Thelateral flanges ,of the angle bars 9 are provided with ali'ned perfo .-7O ing bolts 10 whereby the several sections may be securely fastened together when mold is s et up for use and readily detest 1 and compactly assembled fon transportation or shipment; Theopposite longitng'iili111 '75 edgesof each section 8 are also reinforcedbyij longitudinal angle bars 11 preferably' curv di to conform to the shape of the sections'8andfterminating flush with the adjacentvertical 5' edge of the angle bars 9 so as to prevent-the '80 sections 8 from spreading or buckling when the cement is introduced into themolding compartment. As a means for alining the several-sections when the mold is set up'for use the lowerlon'*8 5 gitndinal flange 1'1 of each section is provided with a dependingintegral lug 12 preferably formed by slitting the metal, as indicated at- 13, said lug 12 being adapted to entera correspondingly shaped recess l l'forn e' din theh'go upper reinforcing bar of an adjacent-section whereby said sections areefl'ectually loc ked against lateral displacement.
